Is that pinout looking from the topside of the relay or from the bottom (where the pins are)? You can find out if the relay matches the pinout with an ohmmeter. Resistance between the coil L1-L2 leads should be low but not zero, maybe a few hundred ohms. The COM-NC will read shorted, near zero. The NO lead should not give any reading with respect to any other lead unless the coil is energized.

You can make any relay operate as a buzzer: connect V+ to NC, COM to L1 or L2, and ground the other coil lead. The relay will turn on, breaking the connection and allowing it to turn back off. Then when the armature comes to rest on the NC contact it will turn on again, repeating the process.

If you operate a 5V relay off 12V, it will still actuate. It will draw more current than intended and probably overheat. I say all of this becaus there is a good chance your relay isn't bad. It might be you have the wrong pinout, or the wrong part was in the package when you bought it.

the pinout is looking from the bottom and is correct since there is only 5 pins. the coil reads 0.06 on 20k ohm. I got 5v+ signal going to L1, 12- going to L2, and 12+ to COM, but still no power switched to NO. I checked the power output on my signal and it is not 5v its like 3.54 and think this is the problem. I think I might have to get another relay that can trigger off of 3.54.
